Some highly sterically hindered organosilicon compounds
The chemistry of organometallic compounds with bulky ligands such as (Me3Si)3C(Tsi) or (Me2PhSI)3C(Tpsi) attached to a variety of metal centres is reviewed. The compounds Tsi2M (M = Zn, Cd, Hg) and the rare two co-ordinate TsiMn show exceptional thermal and hydrolytic stability. The corresponding alkylmetal halides form ring or cage structures. In a range of new boron compounds the structures o...
متن کاملThe electrochemical behaviour of ferrocene in deep eutectic solvents based on quaternary ammonium and phosphonium salts.
The electrochemical behaviour of ferrocene (Fc) is investigated in six different deep eutectic solvents (DESs) formed by means of hydrogen bonding between selected ammonium and phosphonium salts with glycerol and ethylene glycol. Combinations of cyclic voltammetry and chronoamperometry are employed to characterise the DESs. The reductive and oxidative potential limits are reported versus the Fc...

متن کاملPractical catalytic method for synthesis of sterically hindered anilines.
A practical catalytic method for the synthesis of sterically hindered anilines is described. The amination of aryl and heteroaryl boronic esters is accomplished using a catalyst prepared in situ from commercially available and air-stable copper(i) triflate and diphosphine ligand. For the first time, the method can be applied to the synthesis of both secondary and tertiary anilines in the presen...
متن کاملIncreased efficiency in cross-metathesis reactions of sterically hindered olefins.
Efficiency in olefin cross-metathesis reactions is affected upon reducing the steric bulk of N-heterocyclic carbene ligands of ruthenium-based catalysts. For the formation of disubstituted olefins containing one or more allylic substituents, the catalyst bearing N-tolyl groups is more efficient than the corresponding N-mesityl catalyst. In contrast, the formation of trisubstituted olefins is mo...
